He was the son of Filipino film actor, composer, and musician Tito Arevalo and Guadalupe Francisco.

[1] He attended the Legarda Elementary School, San Beda College and Ateneo de Manila where he studied Business Administration.

His major screen debut was in Gerardo de Leon’s Huwag Mo Akong Limutin (1960), which was banned by censors for perceived immoral themes.

[1] Aside from acting, Arevalo also served as the anchor of ABS-CBN's news bulletin Balita Ngayon along with Mel Tiangco.

This followed after the station resumed broadcasting following the People Power Revolution in 1986, and lasted until the program's replacement by TV Patrol in 1987.
